Abstract

The invention relates to a magnetic valve which is caulked on a caulking area by means of a fluid block. The valve includes a capsule, a magnetic assembly, an anchor and a valve insert which guides a magnetic flux which starts from the magnetic assembly in an axial manner via an airgap in the direction of the anchor. The capsule includes a lower area which is displaced in an overlapping manner on the valve insert. The overlapping area of the capsule extends in the direction of the caulking area, the magnetic assembly guides the magnetic flux via the capsule into the valve insert, the capsule is caulked with a valve bushing on the caulking area by means of a fluid block and a bushing is inserted into the capsule.

Claims

exact text as granted — not AI-modified
1. A solenoid valve, which is caulked to a fluid block in a caulking region, the valve comprising a capsule, a magnet unit, an armature, and a valve insert that conducts a magnetic flux, which is introduced by the magnet unit axially via an air gap in the direction of the armature, the capsule having a lower region that is slid in overlapping fashion onto the valve insert, the overlap region of the capsule being elongated in the direction of the caulking region, the magnet unit introducing the magnetic flux into the valve insert via the capsule, the capsule being caulked to the fluid block in the caulking region by means of a valve bushing, and a sleeve inserted into the capsule, the valve further comprising a tappet and an associated tappet guide, movement of the tappet being guided by the valve insert and/or by the sleeve by means of the associated tappet guide, and wherein the valve insert comprises a round internal bore for the tappet guide and the tappet comprises volume compensation grooves let into it between a tappet top and a tappet bottom. 
     
     
       2. The solenoid valve as recited in  claim 1 , further comprising a return spring resting against the sleeve or the valve insert and returns the tappet to its initial position. 
     
     
       3. The solenoid valve as recited in  claim 2 , wherein the return spring is situated in the vicinity of the air gap between the armature and the valve insert. 
     
     
       4. The solenoid valve as recited in  claim 1 , wherein the stroke of the tappet is adjustable by axially sliding the capsule and/or sleeve. 
     
     
       5. The solenoid valve as recited in  claim 2 , wherein the stroke of the tappet is adjustable by axially sliding the capsule and/or sleeve. 
     
     
       6. The solenoid valve as recited in  claim 1 , wherein the air gap between the valve insert and the armature is changeable by sliding the valve insert in the capsule with the inserted armature. 
     
     
       7. The solenoid valve as recited in  claim 1 , wherein the sleeve has an outflow bore. 
     
     
       8. A solenoid valve, which is caulked to a fluid block in a caulking region, the valve comprising a capsule, a magnet unit, an armature, and a valve insert that conducts a magnetic flux, which is introduced by the magnet unit axially via an air gap in the direction of the armature, the capsule having a lower region that is slid in overlapping fashion onto the valve insert, the overlap region of the capsule being elongated in the direction of the caulking region, the magnet unit introducing the magnetic flux into the valve insert via the capsule, the capsule being caulked to the fluid block in the caulking region by means of a valve bushing, and a sleeve inserted into the capsule, wherein the valve further comprises a tappet and an associated tappet guide, movement of the tappet being guided by the valve insert and/or by the sleeve by means of the associated tappet guide, and wherein the tappet is embodied as fully round and the valve insert for the tappet guide comprises volume compensation grooves let into it between a tappet top and a tappet bottom. 
     
     
       9. The solenoid valve as recited in  claim 8 , further comprising a return spring resting against the sleeve or the valve insert and returns the tappet to its initial position. 
     
     
       10. The solenoid valve as recited in  claim 9 , wherein the return spring is situated in the vicinity of the air gap between the armature and the valve insert. 
     
     
       11. The solenoid valve as recited in  claim 8 , wherein the stroke of the tappet is adjustable by axially sliding the capsule and/or sleeve. 
     
     
       12. The solenoid valve as recited in  claim 8 , wherein the air gap between the valve insert and the armature is changeable by sliding the valve insert in the capsule with the inserted armature. 
     
     
       13. The solenoid valve as recited in  claim 8 , wherein the sleeve has an outflow bore.
